Be it known that I, WALTER J. BARRON, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, inthe county of Kings and State of New York', have invented certain new and vuseful Improvements in Type-Vriting Machines, of which the following is a specification.

My invention relates to columnar or tabulating mechanisms, and has for its main object to provide a simple, convenient, and effective construction by which the operator may be assisted to quickly and positively locate the starting-point for a line of figures or other characters to form a column or a series of columns.

In the accompanying drawings,Figure 1 is a front elevation of the upper part of a Remington No. 6 type-writing machine containing my improvements. Fig. 2 is a side view thereof, partly in section and taken onthe plane Y Y of Fig. 1. Fig. 3 is an enlarged perspective view looking from the rear side of part of the carriage release and stop mechanism. Fig. 4 is a vertical section taken at the line X X of Fig. 3. Fig. 5 is a perspective view to show more particularly a modiied construction of stop on the carriage. Fig. G is a perspective view of a locking-dog forming part of the carriage-stop device. Fig. 7 is a perspective view of o ne of the detachable pointers or indicators. Fig. 8 is a perspective view looking from the rear-and somewhat similar to Fig. 3, but showing my invention carried out in still another form and involving the use of a plurality of carriagestops. Fig. 9 is a vertical section showing the manner of adjusting said stops, and Fig.

1 10 is a perspective view looking from the hated by the numeral l.

Serial No. 8,292. (No model.)

confine my description more particularly to the parts having relation to my improvements.

The paper-carriage in its entirety is desig- At its front side the carriage is provided with a roller 2, which travels on a track or Way 3, which in this inl stance is the shift-rail of the machine, and at near its rear side the carriage is providedwith other rolls: 4, which travel on a rod 5, supported on upwardly-extending ears on the top plate 6. Extending rearwardly from the center of the carriage is an arm ,7, that is forked to straddle a sleeve 8, which slides upon a guide-rail 9, supported on posts k10,

rising from thetop plate. The platen is des rack or ratchet-wheel 19 and a backingratchet within a box 20 being provided at the rear end of said shaft, all in the usual manner. Coacting with said rack 19 are the usual feeding and detaining dogs 21 and 22, respectively meunted on a dog-holder (not shown) and arranged to be rocked back and forth at each operation of the key-levers. The carriage is connected by a strapr23 to a springdrum 24, that tends to propel the carriage toward the left; but normally one or the other of the dogs 21 22 engages the rack-wheel, and through the shaft 17, pinion 16, and rack 14. the carriage is prevented from moving under the tension of the spring within lthe drum. When, however, a key is depressed, one dog moves out of thera'tchet-wheel andthe other in, and when the key is released the dogs resume their first positions, and either on the depression or the return of the'key the carriage moves one letter-space, dependent upon whether the dogs are set to give the carriage the natural feed or the reverse feed.

The carriage may be released for rapid movements toward the left under the action Ioo of the spring-drum independently of the escapement mechanism (consisting, primarily, of the dogs and the rack-wheel) by lifting the straight or longitudinally-arranged feed-rack 14 out of engagement with the pinion 16, the rack being attached to the arms 15, which are pivoted to the carriage, as usual.

The construction and operation thus far described are common tothe machine illustrated for embodiment of my invention, which latter may new be specilically described.

30 designates a side bar, which is perforated to take a bearing on the platen-axle 31; 32 another side bar, also perforated to take a bearing on the platen-axle on the other or right-hand end of the platen, and 33 a front bar connected at its ends to the forward ends of said bars 30 and 32, the several bars formingathree-sided frame or bail, the bars 30 and 32 extending forward and backward transversely ofthe platen and the bar 33 being arranged in front of the platen-frame and extending from right toleft longitudinally of the platen and for its entire length and the frame or pivoted hail being mounted to embrace the platen on three sides. This frame may be made from one piece of metal; but preferably I make the several bars of separate parts and form the end bars with ears or lugs and screw them to the front bar, as indicated at 33 in Figs. 3 and 8.

The rear ends of the bars or arms 30 are extended back far enough to engage with pro-l jections 35 on the rack 14 (or on the arms 15) in a manner such that when the pivoted bail or frame is rocked, as by the depression of the bar 33, the inner ends of the arms 30 will rise and lift the feed-rack out of mesh with the pinion 16, and thus release the carriage for rapid movement toward the left. The bar 33, extending for the full length ofthe platen, may be depressed for disengagng the carriage by pressing down upon it at any portion of its length, thus providing a convenient carriage-release-key mechanism, the bar constituting, in effect, an elongated key, so far as the releasing function of the mechanism is concerned. This capacity of the mechanism to release the carriage by pressure upon the bar or key 33 at any point is especially useful or advantageous in connection with column-stop devices, such as will now be described, referring more particularly at this time to Figs. 1 to 7, inclusive.

Mounted upon the bar 33 is a columnstop device, designated as a whole by the numeral 36, comprising, in the example shown, a slide, frame, box, er collar adapted to be moved endwise on said bar, the device shown consisting of a front plate 37, having on each end upper and lower hooks 3S,which are bent over and around the upper and lower edges of the bar 33, so as to embrace the same, and also ofa rearwardly-projecting horizontal lug or ear 39, through a perforation in which passes the vertical stem 40 of a key-piece, the lower end of the stem being threaded to cir/*7,9223

engage with a tapped hole in a dog or ratchetpiece 41 and the upper end of the stem being provided with a button or linger-piece 42, between which and the top of the plate 39 is arranged a coiled spring 43 for keeping the dog or detent device 41 and its attached key normally in a raised position.

Extending along the bar 33 and below the detent 41 is a rack-bar 44 to engage the dctent when the latter is depressed and for the purpose of locking the slide orsleeve 36 in its adjusted position. The slidecarries a depend ing arm 45, which is provided at its lower free end with a dog orstop member 4G, which at certainV times is adapted to contact with a fixed stop or projection 47, arranged on the framework or some part mounted therein. In this case the stop 47 is on an arm 48 and secured to the shift-rail 3 and is the same arm that is now provided in the Remington machine with an index or pointer to coperate with the platen-scale.

A spring 50, coiled around the platen-shaft and bearingat its lforward end against a projection 51 on the release-frame and at its rear end against a portion of the carriage, tends to keep the release-key frame in a raised position and the projection 4G, carried thereby, in a horizontal plane above that of the framestop 47, so that during the course of ordinary Work these two stop members will not come into engagement. Vhen, however, the bar 33 is depressed against the tension of said spring, (and there may be one such spring at each end of the frame,) the stop 46 is carried down into the horizontal plane of the relatively-fixed stop 47, and when the former reaches the latter during the leftward movement of the carriage a contact of the stops is eected, and the carriage is automatically arrested and held against travel to the left as long as the bar is held down. XVhen the bar is released, the stop 4G rises above the top of the stop 47 and the carriage may travel farther toward the left. On the re turn motion of the carriage the stop 46 will pass over the stop 47, assuming that the vibratory stop-frame is in its normal raised position. From what has already been said it will be understood, of course, that when the bar 33 is depressed to bring the stops 4G 47 into coperative relationship the carriage is freed, or detached, so to speak, from its escapement mechanism byaseparation of the rack and pinion 14 and 1G, and hence the carriage is at liberty to travel freely toward the left by the power of the mainspring.

In the construction of adjustable stop shown in the main views it will be observed that the device is adapted to be slid freely along the bar or support 33, and hence to be brought quickly to any desired point tl1ereon, after which it may be locked in its new or adjusted position by the engagement ofthe dog or ratchet with the rack-bar, and thus be held securely against displacement at the time the stops 46 47 strike or engage each IOO IIO

' other.

In operation the userwill find it convenient to grasp the device so that the indexinger rests upon the top of the key or button 42 and then after moving the contrivance to the desired locality to press down upon said button to cause the ratchet devices to interlock and by continued pressure either upon said button or by other lingers upon the edge of the bar or key 33 to cause the-frame as a whole to descend and the stop 46 to be brought into position to engage the stop 47 upon its subsequent arrival at the place where said stop is located, which is preferably in a vertical plane passing transversely through the platen and the printing-point.

In adjusting the slide or stop device along the bar 33 a scale or scales or other indicating devices may be employed to assist the user to arrive quickly at any desired point 0r points. For example, the stop 46 may be shaped, as in the case shown, to act as a pointer and to lie in proximity to the carriagescale 49, whereby said scale may be utilized for an adjustment by said stop. Thus ifit be desired to release the carriage and have it run rapidly toward the left and be stopped by the contact of stops 46 and 47 at, say,60 on the scale the device 36 is slid in the proper direction until the stop or pointer46 registers or alines with 60 upon the scale.V Then the button is depressed and the stop locked to the bar, and the Whole frame is depressed and the carriage released to travel unrestrainedly toward the left. When the stop 46 strikes the stop 47, the carriage will be arrested at a point corresponding to 60 on the scale. The bar may then be released and the carriage rengaged with the escapenient mechanism and put in condition for further travel step by step toward the left.

Glancing'at Fig. 1, it will be seen that lthe right-hand side of the stop 47 serves also as a pointer and by reference to the scale 49 that the carriage has traveled twenty-two letter-spaces toward the left. It will also be observed that the column-stop has been moved or adjusted to the point 60 on said scale. If now the button 42 and the bar 33- be depressed, the stop will be locked, the carriage released, and the stop 46 will travel with the carriage until itstrikes the stop 47, as before explained.

Vhile I have shown a double-toothed dog or detent 4l, a single-dog only may be employed, and instead of having the dog slide to and from the rack 44 it may be mounted upon an arm pi voted to the slide, so as to have a swinging or vibratory movement. Indeed a variety of forms of detents, catches, or locking devices may be employed for holding the normally free-to-Slide stop device in its adjusted or desired working position in place of the construction shown.

As shown at Fig. 5, the plate 37 may be out away and formed or provided with a pointer or index 52 to cooperate with a scale 53, formed on the face of the bar 33, to facilitate the ad justments of the stop. 'p

As a further aid to the user, especially where a piece of Work is being written 'involving a plurality of columns, a series of detachable clips 54 may be employed and arranged at the different points along the scale bar 49 at which the various columns are to commence. For example, as shown at Fig. 1, these pointers or indexes are arranged at 4, 23, 44,7 and 64, the remaining three therein shown being in positions of disuse. In adjusting the column-stop 46 it may be found more convenient or speedy for some operators to effect registration between the stop and the fingers than between the stop and the graduations on the scale; but, aside from this, the placement of the fingers at the points where the various columns are to begin relieves the operator from memorizing these various points or of referring to the paper being written or to side notes or memoranda or to specially-prepared paper-scales.

The indexes 54 are preferably formed of sheet metal, generally of U shape or formed to straddle over or embrace the scale-bar, and pointed or sharpened at their lower ends to more exactly register with the lines or graduations on the scale. These indices 54 may be slid along the scale and grouped at either or both ends thereof` when not desired for use; but they preferably have enough friction or grip to hold them in their adj usted positions. At the same time it will be seen that they may be readily detached from the bar when not wanted for use.

The depressible column-stop frame may be provided with a lateral finger-piece 55, which may serve in place of the usually-employed carriage-release key located at a similar place in the Remington No. 6 machine in order not to interfere with the custom of an operatorfamiliar with this machine when it may be desired to release the carriage for a purpose other than tabular work, it being understood that in this machine the usual release-key is preferably omitted and that the device 37 will notinterfere with the free movement of the carriage when the finger-piece 55 is operated, so long as the dog 41 remains out of engagement with the rack 44.

Referring to Figs. 8, 9, and l0, the depressible carriage-reiease and column-stop frame is provided with a plurality of adjustable stops; but these, unlike the single stop shown'in the other views, are normally not free to be slid or adjusted along said bar, but, on the contrary, are normally engaged therewith. In this construction the stops are intended to be set in the proper positions for a predetermined piece of work or a plurality of columns, and accordingly the stops are constructed differently from the stop iirst above described. Each stop comprises a plate or bar portion, as 37a, having a hook at its upper end which embraces the upper edge of the bar 33", and Y IIO a tooth or dog 33b on its lower end which normally engages a tooth-space formed by a rack 33 on the lower edge of the bar 33. The plate 37 is provided on its inner face with a hook-shaped plate-spring 5G, whose point engages the inner face of the bar 33 and holds the stop device firmly in position thereon. The manner of adjusting the stop upon the bar is illustrated at Fig. 9. The lower end of each plate 37 constitutes a stop, as 46, which is adapted to cooperate with the fixed stop 47 when the frame has been depressed and the carriage released in the manner hereinabove described With reference to other views.

The adjustment of a power-driven papercarriage by means of the ordinary release-key is attended with some difficulties, because the weight of the carriage, combined with the driving-spring tension thereon, renders the carriage likely when put in rapid motion to move beyond the desired point, and in attempting to return the carriage to the desired point there is likelihood of moving it back too far, so that owing to this vibration back and forth about the' point at which it is desired to arrest the carriage undue time is consumed. For this reason it is customary with some operators to bring the carriage rapidly to a point near the desired point and then to feed it along to the right place by one or two taps upon the space-key. One of the principal objects of my invention is to avoid these difficulties and expedite the positioning of the carriage. To this end it Will be seen that lthe device 37 may be not only slid rapidly along the bar 33, but may be instantly1 arrested at any point determined by reference to the scale 49, and then the key which is mounted upon said device 37 may be depressed, so that the carriage is released and may be moved rapidly until arrested by the stop 4:7, the Whole operation requiring much less time and mental labor 'than usual in positioning the carriage.

Inasmuch as several features of my invention may be carried out in other ways, I do not limit the invention to the precise details of construction and arrangement herein set forth.
